RECORD SPORT columnist and Celtic legend Sutton believes the shock departure of Neil Lennon's trusted assistant will be keenly felt at the club.

CELTIC legend Chris Sutton last night labelled Johan Mjallby’s shock departure a major blow that leaves a gaping hole at the club.

Sutton hailed his former team-mate’s contribution following the announcement Mjallby will quit Celtic at the end of the season after helping Neil Lennon to Three in a Row.

The Swede – who has been Lennon’s No.2 throughout his four years in charge – says he is leaving Glasgow in search of “different opportunities“. The 43-year-old had previously been linked with the manager’s job at AIK Stockholm.

And Record Sport columnist Sutton believes the loss of Mjallby will be keenly felt.

He said: “Johan’s departure will leave a massive hole at Celtic.

“He has been a big part of Celtic’s success, both as a player and Neil’s assistant.

“He was a loss to us as a group when he finished playing and he will certainly be a loss to Celtic’s backroom staff.”

Lennon, who must now begin head-hunting a new assistant ahead of the Champions League qualifiers, admitted to being saddened by his former team-mate’s decision to move on.

But Mjallby said: “I have enormous affection for Celtic and it is with sadness that the time to leave has arrived. However, I now leave to seek some different opportunities.

“The club has been part of my life for almost two decades and it was an honour to work in management with Neil, Garry Parker and the players. We have worked hard to once again bring the club success.”

Mjallby was part of Celtic’s four-man management team but Alan Thompson moved on two years ago in acrimonious circumstances and now only Lennon and Garry Parker remain.

Lennon said: “I will be very sad to see Johan leave. He has given us such great service and will always be a big part of Celtic.”

Chief executive Peter Lawwell said: “We wish Johan success. He has worked closely with Neil to achieve great things for the club.”
